翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク NGC 4567 and NGC 4568 ： ウィキペディア英語版 NGC 4567 and NGC 4568 NGC 4567 and NGC 4568 (nicknamed the ''Siamese Twins'' or the ''Butterfly Galaxies'') are a set of spiral galaxies about 60 million light-years away〔 in the constellation Virgo. They were both discovered by William Herschel in 1784. They are part of the Virgo cluster of galaxies. Only one supernova (SN 2004cc) has been observed in the Siamese Twins. These galaxies are in the process of colliding and merging with each other, as studies of their distributions of neutral and molecular hydrogen show, with the highest star formation activity in the part where they overlap. However the system is still in an early phase of interaction.〔(【引用サイトリンク】url=http://adsabs.harvard.edu//abs/2010ASPC..423...26K )〕 They were named "Siamese Twins" because they appear to be connected. == See also == * Antennae Galaxies * Eyes Galaxies 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NGC 4567 and NGC 4568」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
